推荐答案
文档中明确指出，排球不适合下载大量数据。你可以考虑使用替代，如下载管理器。
The documentation clearly states that Volley is not suitable for downloading large data. You can consider using alternate such as the DownloadManager.
排球是不适合大型下载或流媒体业务，因为排球在分析过程中在内存中保存所有响应。对于大的下载操作，可以考虑使用像下载管理器的替代品。
Volley is not suitable for large download or streaming operations, since Volley holds all responses in memory during parsing. For large download operations, consider using an alternative like DownloadManager.
